Discussion Overview

The discussion revolves around determining the values of Vx and Iy in a given electrical circuit figure. Participants explore methods for calculating these values, focusing on concepts related to voltage division and resistor combinations.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant claims to have found Vx to be 8 volts using voltage division but is uncertain about how to find Iy.
  • Another participant suggests that combining resistors in parallel or series may be the most straightforward approach to solving the problem.
  • A different participant questions the placement of the current arrow for Iy, suggesting it may not align with the requirements of Kirchhoff's current law.
  • One participant clarifies that Iy refers to the current through a specific 40-ohm resistor and expresses difficulty in finding Iy despite having calculated Vx through resistance equivalence.
  • Another participant emphasizes the need for the original poster to show their work in order to receive further assistance, indicating that guidelines limit help without visible effort.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the best approach to find Iy, and there are differing opinions on the necessity of showing work for further assistance.

Contextual Notes

There are limitations in the discussion regarding the assumptions made about the circuit configuration and the definitions of terms used, which may affect the clarity of the problem-solving process.

I must determine Vx and Iy in this figure..

Vx=8 v that what i found using voltage division..but how can i find Iy?

thank you

Are you familiar with combining resistors that are in parallel or series? That seems the most straightforward approach.
 
Is your current arrow for Iy, drawn as given in your problem? In your diagram it appears to be right over a node. (Are you familiar with the behavior of current with respect to Kirchoff's current law?)
 
sry the current Iy is for the resistor(40 ohms)..i did a resistance equivalence to find vx..but i cannot seem to fin Iy..please guide me
 
You need to show your own effort to receive more help here. You've gotten as much help as our guidelines allow until you show your work.
